(MC POV)
"Did you know that Takeda-san had a crush on you before today?" I asked Tsuki over dinner after school.
Tsuki tilted her head slightly, "Hmm? Why would I care about someone who isn't Aniue?"
I shrugged, "I thought you might find him charming or something? Maybe you might be interested in him as a romantic partner? He does have the looks and the money as well."
She made a gagging sound, "Bleugh… He doesn't even look like Aniue at all, there's no way I would be interested in him. I'm also not a materialistic girl you know? Besides, Aniue's definitely richer than him."
"Hmm? What does him not looking like me have to do with anything?"
"Ehehe~ Because looking at Aniue makes me the happiest so I wouldn't be interested in anyone else~"
Ugh… Why is she so cute?
I couldn't help but reach out and pat her head for being so cute, causing her to squirm even more cutely.
Only MC would have the idea of making an entire dungeon for the sake of playing with his little sister.
